Xue Kai, Process Technology Department, Dalian Rubber Plastic Machinery Co., Ltd.
Our company is a state-owned listed company specializing in the production of rubber and plastic machinery and equipment. The product parts include wear-resisting, anti-corrosion, high-strength and heavy-duty. It covers most of the types of materials in machining, and the tools used are also diverse. The annual tool consumption is basically 10 million yuan, which is a large tool consumption.
Tool application:
In recent years, the company has undergone relocation, equipment replacement, and entered a stage of rapid development, and the demand for tools has been increasing. Due to the lack of promotion of our domestic tool manufacturers in our company, the indexable tools are basically occupied by foreign brands. At present, the order is WIDIA, SECO, SANDVIK, and the rest are mainly domestic grades of carbide and high-speed steel tools, and the imported tools account for more than half. The indexable tools are mainly face milling cutters, end mills, shallow hole drills, etc. The overall cutters are mainly high-speed steel, mostly drills, taps, reamers, etc.
At the beginning of 2013, our company began to cooperate with Dalian Jingwei Tool Technology Service Company to start the tool cost rectification work. Jingwei Tool is a non-profit service company based on tool application technology and mainly on-site service. With its many years of experience in tool application, it has provided us with valuable guidance in tool application and also brought A large number of useful domestic tools. Through trial cutting, a number of domestically produced tools have been verified to be no worse than foreign brands. For example, we use Fu Nike's CBN blade to process the calender frame (see photo), and get 2 less than the cost increase. ~3 times the feed rate, nearly twice the depth of cut and more than twice the service life, the overall benefits are obvious. At the same time, the drilled shallow hole drill, cast iron disc milling cutter, ordinary steel 45 ° lead angle disc milling cutter, vertical alloy steel 90 ° disc milling cutter, etc., performance is comparable to our original imported brand, and The cost is reduced by at least 50%, which fully proves that the domestic tool technology level has made great progress in most processing areas.

Tool localization recommendations:
At present, the process of localization of tools also reflects some areas worthy of improvement by domestic tool companies:
(1) There is still a certain gap between the “shading blade†and the “machine-clamped ball milling cutter†and the imported brand tools in terms of processing quality and life.
(2) The speed of updating the type and structure of domestically produced tools lags behind that of imported tools.
(3) The strength of domestically produced tools in the market promotion is insufficient, such as tool samples, the number of tool samples is small, and the cycle is long.
(4) Due to the serious loss of personnel in the company's internal research tools in recent years, the level of tool technology has gradually declined. If some professional tool design, manufacturer or technical service manufacturer can go deeper into the enterprise, and guide the specific application details or the special tool transformation, the production efficiency of the enterprise will be greatly improved, and less investment can be used. Achieve better overall benefits.
With the development and integration of technology, the development of domestic tools has also shown a rapid progress. If these manufacturers in China can penetrate into various enterprises and provide special personalized services for their respective production situations, they will find more applications. Demand will promote its research on tool materials, tool structures, development of application technology, and improvement of technology. We hope that more domestic tool manufacturers will visit our company, provide us with more tools for our production, build a personalized tool system for us, and become a messenger of tool application technology, and improve the company's tool application as a whole.

Hot-Melt Bookbinding Adhesives
The term [perfect binding" was created in 1911 to describe the hot-melt adhesive application in the bookbinding process.
At that time, hot melts attempted to overcome the disadvantages of emulsion adhesives while retaining the desirable characteristics of pull strength and flexibility. The driving force toward hot-melt adhesives was their high speed, minimal waste, and relatively low cost.
Our company chaobang adhesive co., Ltd. set up in 1999, we are professional Hot Melt Glue manufacture. Our company has been committed to the Bookbinding Glue for nearly 20 years. In the company's development process, we meet with many different questions and we solved those questions. our company has been developing steadily. We are trying to get better and better. We must do our best to make the good quality product, we must produce the suitable product for the market. Believe us, chose us is right.
